I use the "Google Layers" qgis extension, which works quite well. It
seems that it complies with Google Maps licenses, according to what the
extension's dialog box says:
"
Use of the Google Map Service is subject to a query limit of 1000
unique (different)
image requests per viewer per day.
Google projection
Your QGIS project should be configured to use Google Projection
(EPSG: 900913).
Google projection Proj4 definition:
+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0
+y_0=0 +k=1.0 +units=m +nadgrids=@null +no_defs
Use 'on the fly' CRS transformation to overlay vector data in other
projection.
Sample data
Sample data of Europe in Google projection is located in shp
directory of this
plugin (usually .qgis/python/plugins/GoogleLayers/shp). Use it for
better orientation.

As Georges Marchais (more or less) said: "it may not be your question,
but this is my answer"...
